CONNECTING METHOD FOR SYNTHETIC RESIN TUBE

PURPOSE:To obtain a predetermined connecting quality of a synthetic resin tube and to simultaneously prevent adherence of molten resin to a heating plate by shortening a nonfoaming time of an end of the tube and eliminating an irregularity in a molten state in the case of butt connecting the tube.

Zusammenfassung:	PURPOSE:To obtain a predetermined connecting quality of a synthetic resin tube and to simultaneously prevent adherence of molten resin to a heating plate by shortening a nonfoaming time of an end of the tube and eliminating an irregularity in a molten state in the case of butt connecting the tube. CONSTITUTION:A sealed vessel 1 in which ends of two synthetic resin tubes P1, P2 are contained is evacuated to an atmospheric pressure or less. Ends of the tubes are so heated as not to be brought into contact with a heater 6 to be non-foamed, then melted, and pressed in a tube axial direction in butted state of the ends of the tubes to be fusion-bonded.
